Momo learns of a flower that blooms once every hundred years, but the day before its bloom, it's stolen by a scheming perfumist.
but I don't remember them playing 
nasty pranks like that...
...لكنّي لا أتذكر قيامهم بدعابات مزعجة
Erinner mich aber nicht,
denen Probleme gemacht zu haben.
ma non pensavo proprio 
che facessero scherzi del genere.
Não lembro de causarem
esse tipo de problema...
Раньше они так не поступали.
